UV ink is a type of oil-based ink that is flexible, durable, and environmentally friendly and is often used on packaging and logos.
Follow our easy-to-understand guide to uncover the mystery of UV ink.
What Is UV Ink Made Of?
UV ink, short for ultraviolet ink, is a special type of ink that dries instantly when hit by UV light. Unlike regular ink that soaks into the material or dries slowly, UV ink hardens right on the surface. Here’s what’s inside:
- Monomers & Oligomers: The “building blocks” that form the ink when cured.
- Photoinitiators: Chemicals that react to UV light to start the drying process.
- Pigments: These give the ink its color.
- Additives: Boosts adhesion, flexibility, or gloss.
The result? A tough, vibrant print that looks amazing and lasts.
